Perfection belongs to narrated events, not to those we live. - Primo Levi

He was a physicist, more precisely an astrophysicist, diligent and eager but without illusions: the Truth lay beyond, inaccessible to our telescopes, accessible to the initiates. This was a long road which he was traveling with effort, wonderment, and profound joy. Physics was prose: elegant gymnastics for the mind, mirror of Creation, the key to man's dominion over the planet; but what is the stature of Creation, of man and the planet? His road was long and he had barely started up it, but I was his disciple: did I want to follow him?

It is not at all an idle matter trying to define what a human being is.

"There is no rationality in the Nazi hatred: it is hate that is not in us, it is outside of man.. We cannot understand it, but we must understand from where it springs, and we must be on our guard. If understanding is impossible, knowing is imperative, because what happened could happen again. Consciences can be seduced and obscured again - even our consciences. For this reason, it is everyone duty to reflect on what happened. Everybody must know, or remember, that when Hitler and Mussolini spoke in public, they were believed, applauded, admired, adored like gods. They were "charismatic leaders" ; they possessed a secret power of seduction that did not proceed from the soundness of things they said but from the suggestive way in which they said them, from their eloquence, from their histrionic art, perhaps instinctive, perhaps patiently learned and practised. The ideas they proclaimed were not always the same and were, in general, aberrant or silly or cruel. And yet they were acclaimed with hosannas and followed to the death by millions of the faithful."
